hey all im looking again add 2 more KC's on my truck looking at the rectangle 100 watt and 130 watt im looking to place them where the tow hooks would come out. I have one switch in the cab and thats all i want. my kc day lighters are already 100 watts. I need to know do i need to get new cables for them for 4 lights and new relays or can i just run wires off the ones i have now and new relay and fuses. Im not sure what relay i would need or fuses.

these are what i have

or maybe these because there skinner but i would like to switch out the 55 watts for 100 watts or 130 h3 bulbs

i need sum-one that knows more elctrical work then me i know so much i don't know what wattage would work ect. thx all who can help me in this decision

 

your best and safest bet would be to wire them seperately from the other lights with their own relay and fuse, just use the same switch and wires to control the relays on&off, no risk of meld down that way and you will ensure full voltage too the lights, keeping them bright as possible

 

wouldn't i have to get a new switch or should that little one work or need to get a better one?

 

one switch will be fine if you are controling just relay power, the relays use VERY little power to operate, that is the biggest reason we use them, you can control a large ammount of voltage with a very tiny circuit

 

now i know when i put the wires onto the rocker switch they didn't seem to be happy to come off and only got one off.. if i split the wires and connected the new ones to those would it still work or would i be looking at a melt down?

 

i wouldn't run anything new from the switch, just put your new relay next to the old one and jump the switch wire between the two, and wire everything else seperatly

 

im guessing that would be the green wire comming from the relay? because the white wire needs to be connected to a 12v source u can connect it to come on with high-beams but i like a switch better. but the white wire also runs to the switch... grr confusing sorry if im frustrating ya man.

 

no problems... you want the "switched" wire, from what you said there, it will be your green wire

 

sounds good.. im just trying to think what im goning to do with the other white wire? the white wire has a fuse on it and connects to the relay would i wanna split thw other white wire after the fuse and connect them? dam this so much planning lol

 

here is what you should have, 4 wires on each relay, one is ground, one is power feed to the lights, one will be 12v from the battery and should be fused, and one will go to the switch, then another wirh from the switch to a power source, you can connect the wire from the switch to the relay together between both relays, all other wires should be run seperatly, but you dont need to run anyhting else on the switch circuit, the second white wire wont be used
